collapsible, and the arrangement of such jet,

elements in a well with relation to a packer, it having been determined by experiments that certain types of wells, as for instance, where there is insufficient gas pressure to lift the iuid on where wateris showing, necessitate the use of such jet elements as herein- The jet members include in both instances a series of sets of unrestricted in# clined portsof comparative negligible diameter these ports bein in the instance of the collapsible jet capab e of being closed by a downward movement of the casing and consequent movement of one of the elements comprising same. l

The function and `use of the various component parts heretofore mentioned will more clearly hereinafter appear by reference to r the accompanying drawing forming a part of this specification and wherein like numerals oi' reference designate corresponding parts throughout the several views in wliich:- y

Referring now to the articular construction, and arrangement o' parte, attention is directed to Fig. 1 in which is illustrated a conventional well including the elements Of the present invention. iin this illustration,

articular construction of two thel casing is. indicated b reference character 1, the tubing at 2, an the casing head 3. A acker 4 is shown betweenthe tubing 2 andJ the casing 1, aiid'this packer acts to form a lower chamber 5 and upper chamber 6, within thecasing.

At suitable point-s in the tubing above the packer 4 are arranged the plain jet 7 and the collapsible jet8`,.the former being shown in detail Jin' Fig.,j4 and3..'V` "Y v Theconstruction of the jet 7 which in use is the main working jet, comprises a suitably ixedbody having a central longitudi- Inal passage of reduced diameter at 9 which tapersoutwardly at its opposite ends at 1C and 11 to the internally threaded cylindrical ends of the tubing 2.

ToY permit the convenient drilling of the jet passages 15, the outer face Ofthe jet bod isifornied with circumferential lateral shou ders 16 and 17. Suitably spaced according to the specification of the particular jet as determined by the intended application and use, `which` obviously will alter according to the type of the well and-nature of the field in whichthe wellis located. This variation will also apply in connection with the diameter of the jet. With further reference to the shoulders 16 and 17, attention yis called to the Afact that the diameter of the body of the jet is reduced uniformly from the shoulders 17 downwardly. The portion of the jet body below the shoulder 16 is tapered outwardly at 18 sufficiently to permit movement of the drill in the proper direction. i The collapsible jet 8 includes the tubula body portion 19 formed with the inwardly proJecting annular ange 20 and the internally threaded wall 21. The portion 19 is formed with a plurality ofsets of inclinedl ports 22. Within the tubular body 19 travels the valve member or jet closing means in the form of a headed tube, the head portion 23 of which is of suficient diameter to move freely within the body 19 and at the same time properly seal the ports 22. The shank 24 of the valve member is in substance a conventional tubing section, and corresponds in sha e and diameter to the adjacent tube section utilized in the elevation of the oil. The upper end of this tube is threaded to and the latter in Figs.2v

engage the usual coupling member, Attention is directed to the fact that the upper shoulder and the lower face of the enlarged head 23 are tapered to form annular bearing surfaces. The upper bearing surface y26 engages the corresponding face formed on the yunderl surface of the inwardly projecting ange 2O and the lower bearing surface 2T engages the beveled upper face of the lower element of the cou ling member of the collapsible jet. This ower element of the collapsible jet is a combined coupling for connecting the adjacent tube section and an adjustable stop or seat for the valve member 23. The lower element comprisesa tubular section externally threaded at its upper end 25 to engage the interior threads 21 of the body section, and as previously stated, is formed at its upper end with a tapered seat portion to -receive the valve face 27. The lower end is slightly enlarged and internally threaded at 28 to engage the adjacent pipe section as shown more fully in Fig. 1.

Having thus described the articular construction of the various mem ers forming a part of this invention, it will now be more obvious as to the use and operation of same. For lifting Huid with compressed air or compressed gas such as would be necessary where there is insuilicient as pressure within the well to lift the fluir? or where the capacity of a well is larger than can be obtained by the pump and again in a field that is showing water and it is necessary to keep the water down to save other wells in the vicinity :from being ruined; for this purose two jets are used, one above the other. e top or colla sible jet is placed approximately five hun red feet below the level of the fiuid and the lower or plain jet three 4hundred feet below the collapsible jet and the packer is usually set in the last joint of the casing. Air is introduced through a stuffing box casing head into the well be-- tween the casing and tubing. Its first outlet isthrough the ports of the upper jet which are open the air almost immediately elevates the fluld andthe standin level of the well will commence to fall untll the permanent or working level is reached; at this point the well will usually cease to flow as there is insuilicient Huid above the jet and slippage is taking place (air flowing throughthe fluid). The tubing should now be lowered vto allow the upper jet to collapse and close the ports which will result in thelowe'r or plain jet being thrown in action'. By :this method of stepping down the fluid one` is able to eliminate the high pressure air compressors that are necessary with other forms of air lifts.

It is practically impossible to advise where to set the jets, as every eld varies as to gravity and again every well will vary as to capacity and' working level. Some vwells will exhaust so rapidly that even the lower jet will be exposed, while with others the standing level will be so near the working level it will not be necessary to lower the tubing to close the upper jet. The eliciency, however, can be easily determined at the tank or mouth ofthe well as the iow should be steady and constant.

What I claim asnew and useful and desire to secure by Letters Patent is 1. A. collapsible jet comprising a ported tubular body portion, a sleeve valve reciprocating in said body to close the ports when in lowered position and open said ports when in upper osition, means formed integral with the bo for limitin the u ward movement of t e valve, an an a justable stop for limiting the downward movement.

2. A collapsible jet comprising a body portion, nozzles therein, a solid-walled closure for said nozzles moving in said body, means formed integral with the bod for limiting the upward movement of said closure and an adjustable stop for limiting 90 the downward movement of said closure formed with an internally threaded extension.

.3. A collapsible jet comprising a perforated body portion having an inwardly tapered flange at its `upper end and a stop at its lower end formed with a conical valve seat, a valve member arranged within said body for movement to seal said erforations and adapted to engage said va ve seat. 100
